Which Key ID for Business Card?

[Rippit the Ogg Frog]

Greetings, I just subscribed.

I'm getting ready to have business cards printed, and want to include my 
Key ID on them so that recipients can look up my key from the keyservers.

My old business card had the Key ID F7605786, UID crawford at goingware.com 
  This is a 1024-bit key that I generated with the old Open Source PGP 
way back when.

But I have some hazy memory of generating a 2048-bit DSA key at some 
point, which I think is the key one should use when sending me mail 
these days.

Given the following:

$ gpg --fingerprint rippit at oggfrog.com


pub   1024D/F7605786 1999-01-11
   Key fingerprint = 9B9F 2D03 9996 AF83 9A4F  CB26 20E8 0D0B F760 5786
uid                  Michael David Crawford (aka Rippit the Ogg Frog)
                         <rippit at oggfrog.com>
uid                  Michael David Crawford
                         <michael at geometricvisions.com>
uid                  Michael D. Crawford <crawford at goingware.com>
sub   2048g/1EA551E9 1999-01-11


Which is the Key ID to print on my business card? F7605786 or 1EA551E9?

Or should I generate a new key entirely?

Following is my latest key.

I just used gpg --edit-key adduid to add the first two UIDs, which seems 
to have rendered my key untrustworthy.  Once I'm completely happy with 
my key I'll get some friends to sign it again.

Thanks!
